The 50-year-old actor, who is also the co-producer, shared the poster of the movie directed by Bangladeshi filmmaker Mostofa Sarwar Farooki.
"Here's the poster of Doob .... @EskayMovies #MostofaSarwarFarooki," tweeted Irrfan.
The poster resembles a painting of a mountain with rugged, green terrain, with Irrfan's face superimpsoed on the canvas.
Speculation has been rife in the Bangladeshi and Indian media that the film is a biopic loosely based on late Bangladeshi writer and filmmaker Humayun Ahmed who divorced his wife of 27 years and married an actress 33 years his junior.
Irrfan plays a filmmaker named Javed Hasan who leaves his wife and marries an actress who was his daughter's classmate in school.
Farooki has denied the film is a biopic and is taking matter to court.
